Abstract

The invention relates to an oleogel-forming agent which comprises at least one highly dispersed triterpene. The invention also relates to an oleogel which comprises a nonpolar liquid in an amount ranging from 80% by weight to 99% by weight based on the total weight of the oleogel and an oleogel-forming agent comprising a highly dispersed triterpene in an amount ranging from 1% by weight to 20% by weight based on the total weight of the oleogel. The invention also relates to a method for producing an oleogel.

Claims

exact text as granted — not AI-modified
The invention claimed is: 
     
       1. A method for producing a triterpene-containing oleogel, comprising:
 forming an oleogel using at least one highly dispersed triterpene having an average particle size of less than 50 μm that acts as an oleogel-forming agent in the oleogel, wherein the at least one highly dispersed triterpene is the only oleogel-forming agent in the oleogel. 
 
     
     
       2. The method as recited in  claim 1 , wherein the average particle size of the at least one triterpene is less than 10 μm. 
     
     
       3. The method as recited in  claim 1 , wherein the proportion of secondary agglomerates of the at least one triterpene is less than 20% by weight. 
     
     
       4. The method as recited in  claim 3 , wherein the at least one triterpene has a homogeneous particle size distribution. 
     
     
       5. The method as recited in  claim 1 , wherein the specific surface area of the at least one triterpene is between 1 m 2 /g and 500 m 2 /g. 
     
     
       6. The method as recited in  claim 5 , wherein the specific surface area of the at least one triterpene is between 10 m 2 /g and 100 m 2 /g. 
     
     
       7. The method as recited in  claim 6 , wherein the specific surface area of the at least one triterpene is between 20 m 2 /g and 50 m 2 /g. 
     
     
       8. The method as recited in  claim 1 , wherein the amount of the at least highly dispersed triterpene is more than 80% by weight. 
     
     
       9. The method as recited in  claim 8 , wherein the proportion of the at least one highly dispersed triterpene is more than 90% by weight. 
     
     
       10. The method as recited in  claim 1 , wherein the at least one triterpene has a proportion of more than 80% by weight betulin.
